Terms of Service

Last updated: July 12, 2026

These terms apply to the Deep Fried Labs website, desktop app, and calculator apps (CalcLite and SuperCalc+). By downloading our software or making a purchase, you agree to them.

The products

• CalcLite is free symbolic-algebra software for the TI-84 Plus CE.
• SuperCalc+ is a paid upgrade ($20, one-time) that adds a step-by-step Calculus 1–2 toolkit. The purchase is a lifetime license for personal use, including future updates to SuperCalc+.

Your license

Your SuperCalc+ license is personal. You may install the apps on calculators you own or use. You may not resell, redistribute, or share the app files or your license, and you may not reverse-engineer the software except where the law allows it regardless of this term.

Payments and refunds

Payments are processed by Stripe. If SuperCalc+ doesn't work for you and our support can't get it working, email support@deepfriedlabs.com within 14 days of purchase for a full refund. Refunding a purchase deactivates the associated license.

Academic honesty

Our apps are built for studying and homework. Many standardized tests and some classrooms restrict CAS-capable calculators — it is your responsibility to know and follow the calculator policy of any test or course. Deep Fried Labs is not responsible for consequences of using the apps where they are not permitted.

Your calculator

The apps install through the standard TI app mechanism and do not modify your calculator's operating system. Still, you install and use the software at your own risk.

Disclaimer and limitation of liability

The software is provided "as is", without warranty of any kind. We work hard on correctness, but we do not guarantee that every result is error-free — check your work. To the maximum extent permitted by law, our total liability for any claim related to the products is limited to the amount you paid us.

Trademarks

TI-84 Plus CE is a trademark of Texas Instruments, which is not affiliated with and does not endorse Deep Fried Labs.

Changes

We may update these terms as the products evolve; material changes will be reflected on this page with a new date above. Continuing to use the products after a change means you accept the updated terms.
